Hi,

I'm about to get a Fujinon 210mm CM-W for my Arca-Swiss 6x9 F-line classic. This lens requires a 110mm Copal #1 board. My 110mm Copal #0 boards all have a ridge in the back, that falls in place on the camera. The 110mm Copal #1 board 091000.3 seems to lack this ridge, removing some extra light protection. Would anybody know off this matter?

Cheers,

Sanne
